Notojima Aquarium (のとじま水族館) is located on Notojima Island in Nanao Bay, showcasing the marine life of the Sea of Japan and Noto Peninsula's rich coastal ecosystems. The aquarium's highlight is a 22-meter underwater tunnel through a massive tank containing 20,000 fish including yellowtail, sea bream, stingrays, and sharks — visitors walk through as fish swim overhead and around them. The jellyfish exhibition features 20+ species displayed in illuminated tanks that highlight their translucent, otherworldly beauty.

The facility also includes dolphin and seal shows (4 daily performances), a touch pool where children can handle starfish and sea cucumbers, and a penguin enclosure where Antarctic penguins waddle across artificial snow. The aquarium emphasizes local marine life — exhibits explain traditional Noto fishing methods, display local shellfish and seaweed varieties, and feature the giant Echizen crab (live specimens in winter). The location on Notojima Island (connected to the mainland by bridge) combines the aquarium visit with scenic coastal driving and views of Nanao Bay's oyster rafts and fishing boats.

Insider Guide

Premium
**Underwater tunnel timing:** The tunnel is most impressive when feeding occurs (11:30 and 15:30 daily) — divers hand-feed fish inside the tank, creating concentrated fish activity directly overhead. The yellowtail (buri) swarm en masse, creating a silver tornado effect. Arrive 10 minutes before feeding for best viewing position (center of tunnel). Photography through acrylic is challenging (reflections and distortion) — turn off flash, get close to acrylic to minimize reflections, and use portrait mode to blur foreground scratches. Morning (9:00–11:00) has softer light and fewer visitors than afternoon. **Dolphin show dynamics:** The outdoor stadium hosts bottlenose dolphins performing jumps, synchronized swimming, and trainer interactions. Shows last 20 minutes and are weather-dependent (canceled in strong wind or rain). The dolphins are housed in a netted section of Nanao Bay, giving them semi-natural environment. Front-row seats may get splashed during jumps — attendants warn beforehand. The show has educational components explaining dolphin intelligence and conservation, not just entertainment tricks. For photography, use burst mode to capture jumps (dolphins move too fast for single-shot). **Noto Peninsula day trip route:** Combine Notojima Aquarium with other Noto sites: Start at the aquarium (morning), drive north to Wajima Morning Market (arrive by 11:00, see separate entry), continue to Senmaida Rice Terraces (see separate entry, afternoon light is best), and return via coastal Route 249 with stops at small fishing villages. This 160km loop takes 6–7 hours with stops and showcases Noto's diversity — marine life, crafts, agriculture, and coastal scenery. Rental car from Kanazawa is essential (¥6,000–8,000 per day); buses are infrequent and limit flexibility.
